Some basic information that usually comes with an instrument is:
accuracy range response time sensitivity
sensitivity - many instruments are have a limited sensitivity when detecting changes in the parameter being measured. For instance some cup anemometers, because of their mass cannot detect small wind speeds. The problem gets the worse as the anemometer gets heavier.
Instrument Errors
Some basic information that usually comes with an instrument is:
accuracy range response time sensitivity
range - instruments are generally designed to measure values only within a certain range. This is usually a result of the physical properties of the instruments, such as instrument mass or the material used to make the instrument. For instance a cup anemometer that measures wind speed has a minimum rate that is can spin and thus puts a limit on the minimum wind speed it can measure.

• The fact that openings in naturally occurring membranes are invariably thickened can be easily explained by considering how the lines of force in the membrane must flow around the hole. The increasing density of lines of force around the perimeter of the hole requires that additional material be generated there to prevent tearing.

It is this thickening, around the eyes and mouth,

The fundamental equation for unsteady-state conduction in solids or fluids in which there is no substantial motion is
where thermal diffusivity α is the ratio λ/ρcp; λ is thermal conductivity;ρ, density; and cp, specific heat. If α is large (high conductivity, low density and specific heat, or both), heat will diffuse faster.

练习：英译汉 1）HVAC systems and the associated distribution systems often occupy a significant amount of space. Major components may also require special support from the structure. The size and appearance of terminal devices (i.e., diffusers, fan-coil units, radiant panels, etc.) have an affect on the architectural design because they are visible in the occupied space. 2）The design engineer is responsible for considering various systems and recommending one or two that will satisfy the goal and perform as desired. It is imperative that the design engineer and the owner collaborate on identifying and rating the criteria associated with the design goal.

Commissioning of Variable Air Volume Systems
• Definition: What is Commissioning (Cx) ?
“A quality-focused process for enhancing the delivery of a project. The process focuses on verifying and documenting that the facility and all of its systems and assemblies are planned, designed, installed, tested, operated, and maintained to meet the Owner’s Project Requirements.”
Commissioning Objectives
• Ensure the facility meets the owner’s performance requirements • Provide a safe and healthy environment • Provide optimum energy performance • Provide a facility that can be efficiently operated and maintained • Provide complete orientation and training to facility staff and
ASHRAE Guideline 0-2005, The Commissioning Process
Commissioning Person
– Commissioning is often performed by an independent third-party engineering company.
